Specification of Letters Patent.

Application filed February 28, 1919. Serial No. 279,878.

To all whom t may concern:

Be it known that I, EUGNE SCHNEIDER, a citizen of the French Republic, and a resident of 42 Rue dAnjou, Paris, France, have invented new and useful Improvements in Gun Trail-Carriages with Endless Tracks, which invention is fully set forth in the following specification.

This invention has for its object to provide animproved gun carriage having a single-trail, mounted on endless tracks, the trail being capable of turning on the anchorage of the trail tail as a pivot forV the purpose of training the gun. The carriage proper comprises a platform on which a gun pedestal is pivoted. The trail is mounted on trunnions in the usual manner in said pedestal. The said platform is supported by a framing that stays together the endless` track trucks.

In accordance with this invention the said framing is provided with a guide shaped according to the arc of a circle for the training movements of the platform. This guide has its center at the axis of the trail pivot. An actuating mechanism, such as a worm, journaled in the framing and engaging with a toothed sector formed on the platform, l enables the platform to be moved on the framing. y

A constructional form of this invention is illustrated by way of example in the accompanying drawings in which:

Figure 1 is a side elevation, partly in vertical section along the axis of the trail, of the gun carriage in position for firing.

Fig. 2 is a corresponding plan.

Fig. 3 is a cross section on the line III- III of Fig. 1.

In the example shown, the improved gun carriage comprises a trail A in which'the cradle B, that carries the gun barrel C, is mounted on trunnions in the usual manner. The trail is journaled'by means of an axle D in a gun pedestal E having a pivot pin E1 mounted rotatably in the center of a platform F. This platform is supported by a framing G which stays together the two endless-track trucks J and K. The trail A is arranged to bel capable of pivoting on an anchorage for the trail tail, consisting for instance of a platform H provided with a pivot pin I with which the tail eye a 1s engaged. The platform I-I is anchored to the ground 1n the usual manner by means of stakes la According to the present invention the framing G is provided with a curved guide` that is to say, a guide Gl---G2 having the shape of an arc 0f a circle centered at theV axis of the ivot pin I. lThe trail is shown Ain position 'or firing, that is to say, situated Aaround the pivot pin I, without shifting the endless tracks or the platform G that stays the latter together. This rotation may be effected for instanceV by means of the mechanism -shown which` comprises a worm L journaled in the framing G, and engaging with a toothed sector M that is concenv tric withthe guide G1--G2`and is formed or fitted on the platform F; A hand crank L1 is fixed on the shaft of the wormL for the purpose of rotating the platform Fin the desired direction.` Y

The framing G may 'be provided at its ends with devices g forrthe attachment of any suitable means of traction, for the purpose of rotating the gun carriage as a whole around the pivot pin I when it is desired to train the gun through a large angle.

In the constructional form shown in the drawing, the movement of the platform F in the guide @r1-G2 is facilitated by the provision on the framing G of conical tracks G3, Gt, which are concentric with the guide, and over which are adapted to run truncated conical rollers- N whose axles are journaled in brackets O on which the platform F rests elastically.

What I claim is l. A single-trail gun carriage with endless tracks, of the type wherein the trail is adapted to pivot around the trail-tail anchorage for the purpose of training the gun, comprising a movable platformV on which is pivoted a gun pedestal and carried by a framing that stays the endlessltrack trucks together, characterized by the features that the said framing 4is provided with a, guide,

infv the shape of an arc of a circle, for the said platform, said circle having its center at the axis of the pivot pin of the trail.

2. A gun carriage as claimed in claim 1, comprising an actuating mechanism including a Worm journaled in the framing, and engaging With a too'thed sector formed on thevplatform, for the purpose of shifting the said platform in the said framing.

3. A zgun carriage as claimed in claim l, wherein the curved guide for the platform comprises concentric conical tracks for truncated conical rollers journaled in brackets on which the platform rests elastically.

4. In a trail gun carriage provided With endless tracks and adapted to pivot around an axis at the. trail-tail anchorage, a framing connecting the trucks of the endless tracks and provided With an arc-shaped guide, and a gun-carrying platform movable on said guide.

5. In a trail gun carriage provided With endless tracks and adapted topivot around an axis at Vthe trail-tail anchorage, a framing connecting the trucks of the endless tracks and provided With an arc-shaped guide having its center at said axis, a platform movable on said guide about said axis, and a gun pedestal pivotally mounted on said platform.

6. In a trail gun carriage provided with endless tracks and adapted to pivot around an axis at the trail-tail anchorage, a framing connecting the trucks of the endless tracks and provided With an arc-shaped guide, a guncarrying platform movable on said guide, and means to move said platform with respect to said framing.

7. In a trail gun carriage provided With Copies of this patent may be obtained for endless tracks and adapted to pivot around an axis at the trail-tail anchorage, a fra-ming connecting the trucks of the endless tracks and provided With `an arc-shaped guide, a gun-carrying platform movable on said guide, a sector on said platform, and a Worm journaled on said framing for operating said sector to move said platform.

8. In a trail gun carriage provided With endless tracks and adapted to pivot around an axis at the trail-tail anchorage, a framing connecting the trucks of the endless tracks and provided Vwith an arc-shaped guide, a gun-carrying platform movable on said guide, and rollers intermediate said platform and framing.

9. In a single-trail gun carriage provided with endless tracks and adapted to pivot around an axis at the trail-tail anchorage, a framing connecting the trucks of the endless tracks and provided With an arc-shaped guide, a gun-carrying platform movable on said guide, conical tracks on said framing concentric With said guide, and conical rollers on said platform coacting with said conical tracks.

10. In a trail gun-carriage provided with endless tracks and adapted to pivot around an axis at the trail-tail anchorage, a framing connecting the trucks of the endless tracks and provided With an arc-shaped guide, a gun-carrying platform movable on said guide, tracks on said framing concentric With said guide, rollers on said platform coacting With said tracks, and elastic means intermediate said rollers and platform.`

In testimony whereof I have signed this specification.
